Patented Dec. 9, 1941 LIQUID DISPENSING DEVICE William M. Carroll, FortWayne, Ind., assignor to The Wayne Pump Company, Fort Wayne, Ind., acorporation of Maryland Application March 7, 1935, Serial No. 9,760

14 Claims.

This invention relates to computing liquid dis-' pensing devices andparticularly to computing gasoline pumps, and particularly to the typewherein liquid is adapted to flow under pressure through a dispensingline, through a liquid measuring device of the continuously measuringtype, and thence through some type of dispensing control valve which isoperable to control the dispensing action.

The present application relates to improved features of invention of thedevice shown in my prior patent wherein I have disclosed a liquiddispensing pump provided with means for obtaining the power foroperating the register from the pump and not from the meter, the meterin such instances merely serving as a control. The advantage in my priorconstruction lies in the fact that it eliminates the necessity ofdirectly connecting the register and driving the register from themeter, which is obviously unsatisfactory in many instances because ofthe necessity of taking power from the meter to operat the register andwhereby the drag resultantly placed upon the meter seriously interferedwith its accurate metering function. The power required for driving aregister varies considerably during e., during transfer operation thepower required to drive the register is considerably increased over thatrequired when transferring is not being effected. If the register isdriven directly from the meter, not only is there a drag placed upon themeter, but this drag is uneven, and the meter will consequently act as afluid pump delivering a variable load which destroys the accuracy andreliable functioning of the meter. In my prior patent I thereforedisclosed a construction whereby the register was operated by anindependent source of power rather than directly from the meter, and Iprovided, at the same time, a construction whereby the register movementwas necessarily directly proportional to the movement of the meter.

One of the objects of my present invention is to provide a constructionwherein registering mechanism and/or recording mechanism of the pump areoperated from a source of power independent of the driving energy of themeter, wherein any given increment of movement. of the meter shaft isutilized in conjunction with the independent prime mover to produce aproportional and corresponding increment of movement of the means foractuating the register.

Another object of my invention is to provide an improved construction ofcomputing pump wherein the registering and/or recording mechanismthereof is operated from a source of energy entirely independent of themeter and wherein during the operation of the meter there is acontinuous valve connection between the pump and the registering and/orrecording mechanism or between an independent prime mover and theregistering and/or recording mechanism.

Another object of my invention is to provide a computing type ofdispensing pump wherein the registering and/or recording mechanism isoperated from an energy source entirely independent of the operatingenergy of the meter and wherein a construction is provided whicheliminates the necessity of a power reservoir between the prime moverand the register so that the prime mover is directly connected to theregister for providing the sole actuating means for the registeringand/or recording mechanism and wherein the meter constitutes merely agoverning agent.

Yet another object of my invention resides in providing a computing typeof pump wherein the registering and/01' recording mechanism is actuatedby a prime mover providing a source of actuating energy independent ofthe driving energy of the meter and wherein the thrust imparted to theshaft for operating the registering and recording mechanism is directlyproportional to the speed of the meter.

Yet another object of this invention is to provide, in connection withsuch type of pump, means for accumulating, recording, registering andindicating the amounts of liquid dispensed and the amounts of moneysreceived, wherein the energy to operate the same i directly derived froma source independent of the meter.

Another object of my invention is to provide a computing and/orrecording and registering pump of the above character wherein thecomputing and accumulating devices, while operating in correspondencewith the amount, of liquid dispensed, are actuated in such a way thatthe movement of the measuring device or meter is not utilized as asource of power for operating these devices.

Another object of my invention is to provide a registering device for aliquid dispensing pump wherein the device is operated under the controlof the meter but without taking power from the meter.

Still another object is to provide novel means to control the registerautomatically to accumulate the amounts of the transactions.

A further object is to provide novel means for automatically resettingthe indicators.

Another object of my invention is to provide power mechanism forresetting the registers to zero.

A further object of my invention is to provide power means forautomatically resetting the registers to zero when the hose nozzle isremoved from the hose hook.

Yet another object of my invention resides in providing a computing andregistering mechanism for liquid dispensing devices which not onlyindicates the number of gallons dispensed to any particular customer,but also the price per gallon and also the total amount of moneyinvolved in that particular transaction, and wherein the computing andregistering devices are driven from the pump motor or some other primemover whose source of energy is independent of the meter.

Yet another object of my invention resides in providing a computing pumpfor a liquid dispensing system, such as a gasoline pump, where-' in theface of the clock mechanism includes three variable dials, one of whichwill automatically show the amount of liquid dispensed at any particulartransaction, the other of which may be variably set to show the priceper unit amount at any particular time and the other of which dial showsthe amount of the transaction in dollars and cents.

Another object of my invention is to provide a mechanism for adjustingthe unit price indicators which at the same time sets the pricecomputing mechanism so that it will compute at the indicated unit price.

Yet another object of my invention resides in providing a computinggasoline or liquid dispensing pump involving a clock face having atleast three setsof dials, the upper dial being arranged to show theprevailing price per gallon including tenths of a cent, and'wherein theother two dials are disposed beneath and to each side of the firstmentioned dial, one of said set of dials showing the number of gallons,including tenths of a gallon, and the other the total cost of thetransaction including dollars, tenths of dollars and cents.

Another object of the invention is to provide an interlocking price pergallon feature, so that when the price per gallon is set up on theindicators. the computing mechanism will automatically be set to computethe total price at the set up price per gallon.

A further object of my invention is to provide printing means which willmake a record of each individual dispensing transaction.

Another object of my invention is to provide means to record on a salesslip at the termination of a dispensing operation, such data as thetransaction number, date, operator identification symbol, unit and totalprice, gallons of liquid dispensing and any other necessary or desirabledata.

Yet another object of my invention is to provide power means foroperating the recording means.

In general, my invention includes a liquid dispensing pump, specificallya gasoline dispensing pump which includes accumulating and indicatingdevices operated by power independently of the meter, and therefore, nottaking its power from the operating meter, but which is, at the sametime, under the control of the meter whereby to accumulate and indicatethe quantity of the fluid dispensed, the price per unit and the exacttotal amount of the transaction. Registering mechanism is provided toregister the quantity, price and amount and/or alternatively, printingmechanism may be provided to print the quantity, price and amount on aninserted slip, and on a record slip, which may be retained in themachine. There is also provided a total registering mechanism and/oralternatively a total printing mechanism whereby the total number ofgallons sold and the total amount of money received may be registered,and/or alternatively, printed on an inserted slip. The accumulatingmechanism is under the control of a price-setting device which, whenadjusted, determines the amount to be added into each denominationalorder accumulator wheel at each rotation of the counter shaft.Mechanisms are also provided to count and print the number of gallons offluid dispensed and to print the date, consecutive number of thetransaction and a character to identify the attendant.

In the present invention I have preferred to show ancillary mechanismwhereby the machine is normally locked and set in operation by theremoval of the dispensing hose from a suitable support which effects theclosing of a switch to start an electrical motor in operation and alsowhereby removal of the hose in addition initiates a reset operation toreset the indicators, detail money counter and the detail quantitycounter to zero, thus clearing these counters of the amounts placedthereon at the last dispensing operation. The resetting is completedquickly and before the attendant is ready to dispense fluid to the nextcustomer. It is obvious that the main features of my invention may ormay not be used with these details, as desired.

By referring to Figs. 1 and 15 I have shown one particular type ofmechanism for carrying out the broad features of my invention. In short,I have shown the device as a gasoline dispensing pump which includes ahousing 2 through which a supply line 4 passes upwardly from anydesirable source of gasoline supply. This liquid flow line connects withthe inlet side of a liquid forcing means, preferably in the form of anelectrically driven pump 8 having a pulley 8 driven by a belt 12 fromthe pulley of a motor M. The discharge side of this pump discharges intothe usual type of air release chamber l6 which, in turn, passes theliquid, such as gasoline, through a pipe I8 through meter 49 which, aswill hereinafter more fully appear, may be of any desired type orconstruction. From the meter the liquid is passed by means of pipe 20through the customary sight-glass 22, thence through the usualdispensing hose 24 which is provided with a valve-controlled nozzle I56.In addition, the pulley of the electric motor I4 is providedwith a belt30 passing around a pulley or drive wheel 3| on a shaft 32 hereinafterreferred to, whereby the accounting mechanism about to be described maybe driven from the same electric motor which drives the pump. It may beunderstood, of course, that one electric motor may be utilized fordriving the pump, and a separate electric motor may be utilized fordriving the shaft 32 hereinbefore mentioned.

With reference to shaft 32, by inspection of Fig. 2, it will be seenthat this shaft is rotatably mounted in frames 33 and 34 suitablysupported in the machine in any desired manner. One illustratedconstruction is shown in Fig. l. The shaft 32 is operated at a givenspeed, for example, 90 revolutions per minute. A gear 35 on shaft 32,meshes with another gear 36, which is rotatably mounted on a shaft 31.Gear 35 has secured to its side a clutch shell 38. Likewise rotatablymounted on the shaft 31 is a clutch disc 39 carrying rollers 40projecting between the clutch shell 38 and a clutch cam 4| which issecured to shaft 31. A beveled gear 42 is secured to the side of thedisc 39 and meshes with a beveled gear 43 fast on a vertical shaft 44.Shaft 44 has a gear 45 fast to its lower end. This gear is shown in Fig.l as meshing with a gear 46, which in turn meshes with agear 41 securedto the upper end of meter shaft 48. As is well known, this latter shaftis adapted to be rotated when liquid is flowing through the meter 49.The foregoing train of gears transmits any rotation of the meter shaft48 to the gear 42 and the clutch disc 39 whereby to rotate this disc 39in the direction of rotation of the clutch shell 38 and at such a speedthat the disc 39 makes one rotation for each one tenth gallon of liquidpassing through the meter. Obviously, by suitably proportioning themeter and the gear ratio, other arrangements may be had.

As long as there is no flow of liquid through the meter 49, the shaft 44and consequently the clutch disc 39 remains stationary with the shell 38rotating freely over the rollers 40. When, however, liquid flows throughthe meter the shaft 48, shaft 44 and disc 39 make one rotation for eachone tenth gallon of liquid passing through the meter. Rotation of theclutch disc 39 by the meter shifts the rollers 40 bodily into engagementwith the clutch cam 4! thereby causing the continuously and relativelyfast rotating drive shell 38 to rotate the shaft 31 but always at thesame speed as that of the meter shaft 48, i. e., one rotation for eachone tenth of a gallon of liquid flowing through the meter. Thus it isobvious that any given increment of movement of the meter shaft resultsin a proportional and corresponding increment of movement of shaft 31for driving the computing mechanism and it is also obvious that thethrust imparted to the computing mechanism shaft 31 is directlyproportional to the speed of the meter extension shaft 44 and thatduring the operation of the meter there is a continuous power connectionbetween the pump or pump motor or even from an independent motor, andthe registeringmechanism. so that the prime mover is directly connectedto the register mechanism for providing its sole actuating means. Therotation of shaft 31 is utilized to operate the accumulating,registering, printing and indicating mechanisms, and it will be observedthat the power for actuating these mechanisms is derived solely andwholly from the pump motor or other source of power, and is not takenfrom the meter shaft.

There are four accumulators provided in the machine. They comprise adetail gallon accumulator for the purpose of accumulating th number ofgallons of liquid dispensed at each transaction, a detail moneyaccumulator to accumulate the amount of money received at eachtransaction, a total gallon accumulator to accumulate the total numberof gallons dispensed in a given period, and a total money accumulator toaccumulate the total amount of money received for a given period. Thedetail accumulators are adapted to be reset automatically at eachoperation, whereas the total accumulators are reset at the end ofcertain periods of business in order to ascertain the totals for thatperiod.

By referring to Fig. 4 it will be observed that the detail moneyaccumulator includes a plurality of denominational order printing wheels56, 51 and 58, rotatably mounted on a shaft 59 supported in the frames34 and 35. Wheel 55 is the one cent wheel, Wheel 51 is the ten centwheel and wheel 58 is the one dollar wheel. Attached to each one ofthese several wheels is a gear which meshes with another gear on acounter shaft 83. There are three of such gears on the counter shaft-60,SI and 62. An actuator is provided to drive the gear 60 for the one centwheel 55, the amounts being accumulated on the higher order wheels 51and 58 by transfer mechanism.

Bearing in mind that the liquid is measured in one tenth gallons, theamount of money received is likewise accumulated in one tenths of theprice per gallon. For instance, assuming that the price is $0.163 pergallon, 80.0163 is accumulated for each one tenth of a gallon dispensed.In order to accumulate this amount, two additional gears 84 and areprovided to accumulate the tenths and hundredths of cents respectively.However, since it is not desired to indicate or print these fractions ofa cent, no printing or accumulator wheels are associated with thesegears. The hundredths of a cent order transfers to the tenth of a centorder, and the' laTter transfers to the one cent order.

The actuators include arms 88, 81 and 88 for the hundredths of cents,tenths of cents and the cents order. These arms are secured to, inspaced relation, along the drive shaft 31 (see Figs. 4 and 5) and arespaced about its shaft 90 degrees apart.

Each of th arms 86, 81 and 88 carries a roller 89, which as the shaft 31is-driven in the manner hereinbefore described, in a counter-clockwisedirection, successively contacts arms 18, H and 12..

These arms are pivotally mounted on and in spaced apart relation alongthe shaft 83 whereby to rock these arms clockwise through angles of 90degrees. As soon as the rollers 69 escape their respective arms 18, 1|and 12, springs 13 restore said arms to their normal positions, whenthey are stopped by the frame 14, mounted on the reset shaft 15, and ashaft 18. Each of the arms 18, II and 12 carries a spring-pressed pawl11 having an ear bent at right angles thereto, adapted to rest on aperiphery of a price setting segment 18. Three segments 18 are provided,one for each of the hundredths, tenths and units of cents denominationalorders. These segments are set manually by levers 19 mounted on theshaft 31, and which levers 19 have integrally formed therewith segments88, meshing with segments 81, 88 and 89 (see Fig. '7), on the shaft 83.The segment 81 is secured to a segment 98 which meshes with the pinion9I fast onto shaft 92 on which is also fast a pinion 93 meshing withteeth on the segment 18, or the hundredths, of cents segment. Thesegment 88 is secured to the side of a segment 94, which meshes with apinion 95 fast on a shaft 98 having a pinion 91 fast thereon, meshingwith the tenths of cents segment 18. The segment 89 is secured to asegment 98 fast on the shaft 83 to which shaft is also fast a segment 18for the cents denomination order. By means of the levers 19 and themechanisms associated therewith, the segments 18 may be individuallyadjusted according to the current price per gallon of the liquiddispensed.

In some'instances I desire to print the price per gallon on a salesslip. To accomplish this, the segments 18 (Fig. '7) mesh with gears 8|(see Fig. 6) attached to type wheels 82 on shaft 59.v These type wheelsare set according to the adjustment of the levers 19 to print the priceper gallon. Referring to Figure 7 of the drawings, it will be noted thatseven levers 19 are shown and the functions of only the lower three havebeen hitherto described. It will be recalled that these levers set theprice computing mechanism and set printing wheels 82 so that the priceper gallon will be printed on the sales slip. The upper four leversserve to set up other indicia which are to print data on the sales slip.

The uppermost lever operates a sector 18 similar to that shown in Figure6, which in turn operates the wide printing wheel 82' shown in Figure 4.This wheel carries the abbreviated names of the months in a year andserves to print one of the same upon each ticket printing operation.

The second and third levers from the top in Figure 7 operate sectors 18to operate the narrow type wheels 82' of Figure 4 to set up the day ofthe month, so that this data too, will be printed on the sales slip.

A fourth lever 19 is provided and through a sector 18 sets up the typewheel I I2. This wheel carries operator identification characters and isset prior to each operation of the dispensing apparatus so that anindication of the particular operator involved in the transaction willbe printed upon the sales slip issued in terminating the transaction.The pawl 11 carried by the arm 18 (see Fig. 5) is adapted to cooperatewith a ratchet 99 secured to a gear I88, both of which are mounted torotate freely on shaft 83. It will be remembered that the shaft 31 (Fig.5) makes one complete counter-clockwise rotation for each tenth of agallon dispensed, and at which rotation the rollers 89 carried by thearms 88, 81 and 88 successively engage their corresponding arms 18, 1|and 12 to rock these arms clockwise through 90 degree movements. Thepawls 11 travel idly on the smooth peripheries of the segments 18 untilthe.pawl drops off such smooth edge, whereupon said pawls engage androtate the ratchets 99 therewith a distance equal to the remainder oftravel of the arms 18 to 12 inclusive. For instance, if the lever 19 isset at the 5 position, the pawl 11 will pick up the correspondingratchet 99 and rotate the ratchet and gear I88 five spaces. When theroller 89 escapes the arm 18, the spring 13 restores said arm to itsnormal position, pawl 11 moving idly over the ratchet teeth to itsposition on the periphery of the segment 18.

The gear I88 for the one cent order meshes with the gear I8I secured tothe printing totalizer wheel 58 (Figure 5) that is adding 5 onto thiswheel. Assuming that the three price levers 19 are set to 1, 6,3representing the price of 16.3 per gallon, the segments 18 are setcorrespondingly and at each rotation of the shaft 31, 3 will be added tothe hundredths of a cent gear I88, 6 will be added onto the tenths of acent gear I88, and 1" will be added onto the one cent gear I88 andconsequently on the accumulator wheel 58. When the shaft 31 has made tenrotations, that is, when one gallon of liquid has been dispensed, thehundredths of cents order has been reciprocated ten times, and 3 hasbeen added onto the hundredths of cents wheel ten times-causing threetransfers to the tenths of cents wheels, 6 has been added onto thetenths of a cent wheel ten times, causing six transfers to the centwheel, and 1 has been added onto the one cent wheel ten times, causingone transfer to the ten cent wheel. The wheels now stand at 00.1630.

The transfer from a lower denominational order to the next higher orderis effected by a disc I82 (Figure 5) secured to the side of the gearI88. This disc has four projections I83 equally spaced about itsperiphery. The projections I83 cooperate with a gear I84 rotatablymounted on the shaft 92 and secured to one end of a sleeve I85 (Fig. 7)having a gear I88 meshing with the gear I88 of the next higher order toadvance the latter gear one space when the (next lower order gear I88passes from 9" The total money accumulator includes a plurality ofprinting accumulator wheels I81 (Fig. 5.) mounted on a shaft I88, eachwheel having a gear I 89 secured thereto meshing with an intermediategear I III on a shaft II I which gears IIO mesh with their correspondingactuator gears I00. Thus the differential movements of the gears I aretransmitted to the wheels I01 to add thereon the amounts added onto thedetail money wheels 56. It is to be understood that no wheels I01 areprovided in the denominational orders pertaining to the fractional partsof one cent. Transfer from one order to the next higher order isaccomplished by means of the well known Geneva transfer device.Mechanism is provided to disengage the total accumulator from theactuator gears I00 when the item or detail accumulator is reset to zeroin a manner to be hereinafter described.

Item and total accumulators are also provided to accumulate the numberof gallons dispensed at each particular transaction and to accumulatethe total number of gallons dispensed during a given period. The itemaccumulator includes printing accumulator wheels II2 (Fig. 8) mounted onthe shaft 59 and having gears II3 secured thereto which gears mesh withlarge gears II4 on the shaft 63. The tenths of units order gear II4 onlyis advanced one space each time the shaft 31 makes one rotation. Thisrotation of the gear I I4 advances the tenths of units wheel II2 onespace to add one-tenth of a gallon on the accumulator. The tenths ofunits gear I I4 is operated by a disc I I5 having a single projectionI2I on its periphery. The projection I2I at each rotation of the shaft31 advances a gear I22 one space. The gear I22 carries a pawl I23 whichcooperates with a ratchet I24 secured to the tenths gear II4. By meansof this pawl and ratchet the movement of the gear I22 is transmitted tothe tenths gear II4 which in turn advances the tenths wheel II2 one stepfor each rotation of the shaft 31.

The tenths of units gear II4 meshes with a gear I25 on the shaft 92, thegear I25 being fast on a hub I26 (Fig. 7) to which is also fast atransfer disc I21 having a single tooth thereon cooperating with theunits gear I I4 at every rotation of the gear I25 or when the wheel I I2has been rotated ten spaces the single tooth on the disc I21 advancesthe units gear II4 one space. Similarly the units gear II4 meshes with agear I28 on the shaft 31, the gear I28 being hubbed to a disc I29 havinga single tooth thereon cooperating with the tens gear II4 to transferfrom the units order to the tens order.

The total gallons accumulator includes printing accumulator wheels I30on the shaft I08, said wheels I30 having gears I3I secured thereto whichmesh with gears I32 meshing with their respective denominational ordergears II4. Transfer in this totalizer is effected by the usual Genevatransfer gears I33.

Indicating mechanism is also provided to indicate the number of gallonsand fractions of a gallon dispensed at each transaction. Theseindicators are adapted to be reset to zero automat ically at eachoperation of the register.

The indicating mechanism includes a hand I34 (Fig. 9) to indicate thenumber of gallons and a hand I35 to indicate the fractional parts of agallon dispensed. Only one pair of indicator hands I34 and I35 is shown,provision being made to operate indicator hands on both sides of themachine so as to be visible in opposite directions.

The indicators are driven from the shaft 31 which makes one rotation foreach tenth of a gallon dispensed. A gear I36 (Figs. 9 and fast on shaft31 meshes with a gear I31 fast on a shaft I38 disposed first above shaft31 and at right angles thereto. A worm I39 fast on shaft I38 meshes witha worm gear I40 loosely mounted on a shaft I46. The ratios of the gearsI39 and I40 is such that one complete rotation of gear I39 impartsone-tenth of one rotation to gear I40. By means of a multiple discclutch I41 (Fig. 10) the gear I40 rotates a disc I48 secured on theshaft I46 and consequently the shaft I46 which carries at each end ahand I35. These hands are rotated with the shaft I46 one-tenth of arotation for each tenth of a gallon dispensed.

The disc I48 has a single projection on its periphery, which at eachrotation engages a tooth on a gear I49 secured to a shaft I50 androtates this shaft one-twentieth rotation. Two gears I5I and I52 alsofast on the shaft I50 mesh with gears I53 and I54 respectively connectedto the hands I34 by sleeves I55 and I56, thus transmitting the movementof the gear I49 to these hands to advance said hands I34 one-twentiethrotation for each complete rotation of the hands Referring to Figure 1it may be noted that the dial is divided into 20 spaces for indicatingthe even gallons and 10 spaces for indicating the fractional parts of agallon.

In connection with the herein described mechanism, I prefer, althoughnot necessarily so, to provide means for simultaneously resetting theindicator hands and the item accumulator to zero at the beginning ofeach dispensing operation, and in such a manner that the resetting iseffected by a single rotation of reset shaft 15. It will, of course, beappreciated that as to certain broad features of my invention, they arewholly independent of the resetting mechanism and may be utilized ondispensing devices having no resetting mechanism.

However, in the present instance, I have disclosed resetting mechanismwherein, it will be noted, that each of the gears I00, as shown in Fig.5, and each of the gears II4, as shown in Fig. 8, for the item moneyaccumulator and for the item gallons accumulator, respectively, mesheswith gears I51 loosely mounted on the reset shaft 15. The disc I58secured to the side of each of the gears I51 carries a pawl I59 adaptedto cooperate with a longitudinal groove in the reset shaft 15. At theproper time, and by mechanism which is to be described later, the shaft15 receives one counterclockwise rotation (see Fig. 5), during which thegroove picks up all of the pawls I59 and rotates the gears I51 andconsequently the gears I00 and II4 to zero position. The gears I00 andII4 transmit their resetting movement to the accumulator wheels 56, 51and 58, and II 2 to set the latter wheels to zero.

In order to reset the indicators I35 to zero a gear I60 (Figure 10),rotatably mounted on the shaft 15, carries a pawl I6I adapted tocooperate with the groove in said shaft. The reset shaft 15 rotates in aclockwise direction as viewed in Fig. 9, during which the groove thereinpicks up the pawl I6I and gear I 60 rotating these members to zeroposition. The rotation of the gear I60 is transmitted by an intermediategear I62 loose on the shaft I50, to a gear I63 secured to the disc I48,which it will be remembered, is secured to I the shaft I46 carrying thehands I35. This rotation of the shaft I46 advances the hands I35forwardly to zero position.

A similar device is employed to bring the hands I34 to zero. A secondgear I64 meshing with the previously described gear I52, carries a pawlI65 adapted to cooperate with the grooved shaft 15. Obviously when theshaft 15 rotates and the groove picks up the pawl I65 turning the gearI64 to zero position, the movement is communicated to the gear I52, gearI54, shaft I50, gears II and I53 to advance the hands I34 to zeroposition.

The mechanism will now be described for effecting a single rotation tothe reset shaft for the purpose of resetting the accumulators andindicators to zero. A resetting operation occurs at the beginning ofeach dispensing operation and is initiated by removal of the dispensinghose fitting I66 (Fig. 1) from its hook I61. The

hose fitting I66 is normally locked against unau- A link I60 (Fig. l)connects an arm I6I alsofast on the shaft I19 to one arm of a lever I62having its other arm shaped to form a hook which is adapted to cooperatewith a slot in the fitting guard I83 upon removal of the hose fittingI63 from its hook I61 the lever I62 is rocked slightly counterclockwisewhich movement is transmitted by the link I80 to the arm I6I and shaftI19 rocking these members, together with the arm I16 counterclockwise.The arm I16 is normally in contact with a roller I64 (Fig. 11) on onearm of a lever I65 pivoted on the shaft 31. The outer arm of thislever-carries a pawl I66 adapted to cooperate. with one of twoprojections I81 on the periphery of a disc I86 (see also Fig. 2).Rotatably mounted on the shaft 31 adjacent the disc I66 on the shaft 31is a disc I69 carrying clutch rollers I90 projecting between a clutchshell I9I and a clutch cam I92 on the power driven shaft 31. Secured tothe clutch shell I90 is a gear I meshing with a gear I93 fast on theshaft 32.

The disc I89 is provided with two projections I94 one of which normallycooperates witha restraining dog I95 pivoted on a stud I96 and held incontact with the peripheries of the discs I66 and I89 by a spring.

As stated above, removal of the hose fitting from its hook rocks thelever I65 slightly clockwise. At this movement the pawl I86 being inengagement with a projection I61 rocks the disc I68 also clockwise. Theleading edge of the projection I81 is beveled and rocks the dog I95clockwise out of the path of the projection I94 thus releasing disc I69for rotation under action of the clutch springs to render the clutcheffective.

The movement of the lever I65 also closes a switch (not shown) to startthe motor. Secured to the disc I86 (Fig. 11) is a cam I91 with whichcooperates a roller I96 carried on one arm of a lever I99 pivoted on thestud I96 and having its other arm connected by a link 200 to the switchoperating mechanism (not shown).

The clockwise movement of the lever I65 is transmitted by its pawl I66rocks the disc I66 and also the cam I91 clockwise at which movement thecam I91 moves from under the roller I 96 permitting the lever I98 torock clockwise lowering the link 200 to close the switch (not shownithusstarting the electric motor. The

motor rotates the shaft 32 and through the gears I93 and 2M drives theclutch shell I9I and, since the clutch is now effective,the clutch camI92.

The clutch cam I92 has an arm 206 secured to the opposite end of its hub201 which arm carries a roller 206 adapted to cooperate with a segmentalgear 209 (Figs. 7 and 12) pivoted on the shaft 63. The segment 209meshes with a gear 2I0 fast on the reset shaft 15; As the arm 206rotates in a counterclockwise direction (Fig. 12) the roller 206 picksup and rotates the 888- ment 209 one fourth turn in a clockwisedirection. This movement is sufficient to impart to the gear 2I0 andreset shaft 15 one complete counterclockwise rotation to reset theaccumulators and indicators to zero in the manner described above.

As the segment 209 nears the end of its clockwise travel a stud 2 (Fig.'7) thereon strikes an arm 2I2 on the shaft 16 rocking this arm slightlycounterclockwise to bring pawls 2I2 into engagement with the teeth ofsegment 269 to act as a. positive stop for said segment.

With reference to Fig. 7 it will be noted that the four levers 19 shownin the upper part of the figure are arranged so that the operator byshifting the same can set up the identification character of theparticular transaction and the day and the month printing wheels.

As soon as the roller 206 moves out of contact with the segment 206 aspring 2 restores it counterclockwise to normal position where thesegment is stopped by a projection 2I6 thereon striking a stop member2I6 mounted on the shafts 15 and 16.

The oscillatory movement of the segment 209 is made use of to operate aconsecutive counter one step at each operation of the resetting device.The projection 2 I5 on the segment 209 ccoperates with a roller on anarm 2" mounted on the shaft 59 on which are also mounted consecutivecounter printing wheels 2I6. Lined pawls 2I9 carried between the arm 2"and another arm (not shown) coact with ratchets on the wheels 2I6 toadvance the wheel of lowest order one step at each resetting operation.

The resetting operation is completed in onehalf of one rotation of theclutch cam I92 and disc I89. After the projection I61 has passed underthe dog I95, said dog resumes its position on the periphery of the discsI66 and I69 so that when these discs have completed degrees of rotationthe other projection I94 strikes the end of the dog thereby disengagingthe clutch and stopping the rotation of the clutch cam I92.

The resetting operation is efiected very quickly and occurs between thetime the hose fitting is removed from its hook and the dispensingoperation. After the dispensing operation the hose is replaced on itshook and the attendant presses a button 220 which serves to manuallyrock the lever I65 to effect a second 180 degrees rotation of the clutchcam I92 and the arm 206. At this half rotation the arm 206 turns idly tothe position in which it appears in Fig. 12, while other mechanismfunctions to operate the printing mechanism.

The stem 22I of the button 220 is slidably mounted on the shaft I19(Fig. 11) and on a stud 222. The stem 22I carries a stud 223 which uponoperation of the button, engages and rocks counterclockwise an arm 224fast on the shaft I19.

This rocks the shaft and the arm I18 which in turn rocks the lever I85for the purpose above I set forth.

A gear 225 (Fig. 13) secured to the hub 201, which carries the arm 206(Fig. 12) rotates idly at the first movement of the clutch cam I92.However, when the hub 201 is rotated under the control of the button220, the gear 225 meshes with and rotates a gear 226 on the shaft 63. Agear 221 secured to the gear 226 meshes with a gear 228 on the shaft 59.A gear 229 secured to the gear 228 meshes with a gear 230 on a. shaft23I. Secured to the gear 230 is a hammer operating cam 232 and aprinting electro 233. The cam 232 cooperates with a stud 234 projectingfrom a hammer arm 235 pivoted on a shaft 236. A spring 231 holds thestud 234 against the periphery of the cam 232. A platen roller 238rotatably mounted on the shaft 236 cooperates with the electro 233 toprint on an inserted record material. The hammer arm 235 carries aplaten 239 which is adapted to be thrown sharply against all of the typewheels mounted on shaft 59 twice at each operation to take twoimpressions therefrom.

The ratio of the above described train of gears is such that the gear230, cam 232 and electro 233 receive two complete clockwise rotations ateach effective operation of the gear 225. Shortly after the cam 232starts its rotation it releases the hammer arm 235 to its spring 231 toeffect an impression from the type wheels. After this impression ismade, feed discs 240 on the shaft 23l and operated by the gear 230becomes effective to feed the record material toward the left (Fig. 13)The feed discs each have a flattened portion as shown by the dottedoblique line in Figure 13. This flattened portion occupies a positionadjacent to platen 238 at the termination of the printing operation,thus leaving a space for the insertion of the ticket from the left atthe beginning of a dispensing operation. It is also to be noted thatthis flattened portion permits movement of the actuating cam without acorresponding feeding motion of the ticket, thus permitting the platen239 to take an impression while the ticket is motionless.

Platen 238 also cooperates with the discs 240 as a complementary feedroll.

It is contemplated that, instead of inking the register wheels, a tickethaving a carbon sheet overlying it will be used, although any desirableform of inking mechanism may be used as an alternative. Near the end ofthis feeding movement the electro 233 effects its printing on the recordmaterial.

These operations are repeated at the second rotation of the gear 230 toeffect a second impression on the record material which may then besevered between the imprints part being given the customer as a receiptand the remaining part retained.

Any suitable means may be provided to print the total amounts and toreset the total accumulators to zero, none therefore, being shown here-In Figs. 16 to 21 I have illustrated a possibly preferred type ofcomputing pump mechanism wherein instead of printing the items as to theprice per gallon of liquid dispensed, the number of gallons of liquiddispensed and the total cost of the gallons dispensed at that price, Ihave provided mechanism for registering or visually indicating the same.For instance, in Fig. 16 of the drawings I have shown the upper portionof one type of liquid dispensing housing 250 which is substantially likethe housing shown in Fig. 15, and wherein the general mechanism enclosedwithin the housing is the same as shown in Fig. 15, the main differencebeing that in Fig. 16 the items above-noted are registered on the clockface instead of printed and wherein the mechanism for altering the priceper gallon dials is accomplished, not by the levers 19 shownin Fig. 6,but is accomplished by manually turning the price per gallon dialsthemselves. In this manner a very easy and mechanical adjustment may bemade.

Referring to Fig. 16 it will be noted that the clock face 252,preferably comprises an upper opening 254 carrying the legend thereabovePrice-Tax included; to the left and below the clock face is likewiseprovided another window 256, with the legend thereabove Amount, and tothe right of this there is provided a third window 258 with the legendthereabove Gallons. If desired, immediately below these three windows,another window 260 may be provided, through which the totalizer dialsare viewable. Fig. 17, being a view taken on line l1--l1 of Fig. 16,shows at the right hand side thereof the clock face 252 with the priceper gallon window 254 and the amount window 256 with their respectivedials immediately opposite the same. The other window 258, not shown inFig. l1 would be beyond and is identical with window 256. For purposesof convenience, the mechanism and windows are duplicated on each side ofthe pump so that a price per gallon window 254 and the amount window 256and gallons window 258 will be shown on the other or opposite clock dialof the pump standard. In this construction, and for a comparison withFigs. 2 and 3 of the drawings, and for the purpose of convenience, Ishall number the various elements of this construction that are commonwith the constructions of Figs. 2 to 15' inclusive, the same, exceptthat I shall put an additional digit before each number. In other words,I shall call the shaft 32 of Fig. 2, when placed in Figs. 17 to 21inclusive 332. Thus referring to Fig. 17, it will be noted that shaft332 is mounted in suitable bearings in the housing 250 and carries asuitable pulley 331 adapted to be driven by a belt 330, which in turn isdriven from the pump motor 14, all as shown in prior Fig. 15,hereinbefore described. On this same shaft 332 is mounted the gear 335,similar to gear 35 of Fig. 2, and meshing with a gear like 36 of Fig. 2on the shaft 331. In other words, the construction of Fig. 17, insofaras this drive is concerned, is identical with that of Fig. 2, wherebythe shaft 344 is driven and in the manner as shown in Fig. 1, to drivethe shaft 331. By a comparison of Fig. 18 with Fig. 5, it will be seenthat the constructions provided are in the main, substantially alike,except that no printing wheels are provided for this modifiedembodiment. By referring to Fig. 18 and by comparison of the practicallysimilar construction of Fig. 5, it will be evident that when the shaft331 turns in a counterclockwise direction, it will turn the arms 366,361 and 368 in the same direction, and the rollers of these arms willsuccessively contact their respective arms 318, 31! and 312, which arepivotally mounted on shaft 363 to rock these arms clockwise-throughangles of degrees. As soon as the rollers 369 on these arms escape theirrespective arms 310, 3H and 312, springs 313 restore the arms to theirnormal positions, at which position they are stopped by frames 314mounted on reset shaft 315. Each of these arms 310, 311 and 312 carriesa spring pressed pawl 311' having an ear bent at right angles thereto,adapted to rest on the periphery of the price-setting segment 318 (seeFigs. 18 and 21). Three segments 318 are provided, one for each of thehundredths, tenths and units of cents denominational orders. Instead ofsetting these segments manually by means of the levers 19, as shown inFig. 6, in the present instance these segments are set directly by meansof the price per gallon dials as shown clearly in Fig. 21.

fractional numerals from 0" and grading up one tenth up to nine tenths.Obviously other indicia may be utilized if desired. Each one of thedials is provided with a gear 608, 610 and 6 I 2, each gear rigidlyrotating with its dial and each one of these gears in turn meshes withanother gear 614, 6; and 618, each of said latter gears being rotatedupon a sleeve 620, 622 and 624. Each of these sleeves carries a smallgear. Sleeve '620 carries a small gear 626; sleeve 622 carries a gear628 and sleeve 624 carries a gear 630. Each of these gears such as 614,616 and 618, together with its sleeves 620, 622 and 624, and its smallergears 626, 628 and 630 rotates loosely on shaft 316. The series of gears626, 628 and 630 in turn mesh with the respective segments 318 on theshaft 363 as hereinbefore described, whereby upon turning in one of theprice per gallon dials, the corresponding segments 318 will be shifted acorresponding amount on the shaft 363. Each gear 608, 610 and 612likewise meshes with a corresponding gear 632, 634 and 636, whichcarries rigidly therewith a beveled pinion 633, 640 and 642, said latterbeveled pinions in turn engaging beveled pinions 644, 646 and 648mounted on sleeves 650. Inasmuch as these constructions are all similar,only one need be referred to. These sleeves 650, as shown clearly inFig. 1'1, drive another beveled pinion 652, which in turn drives apinion 654 mounted on a gear 656, which meshes with a gear on the sideof the price per gallon dial exactly like gear 608. This gear 608, asbefore stated, turns with the price per gallon dial 602.

Each of the pawls 311 carried by its arm 310 is adapted to operate witha ratchet 399, each secured to a gear 100 and mounted to rotate togetherfreely on the shaft 363. It will be re membered that the shaft 331 makesone complete counterclockwise rotation for each tenth gallon dispensedat which rotation the rollers 369 carried by the arms 366 to 368inclusive successively engage their corresponding arms 310 to 312inclusive to rock these arms clockwise through 90 degrees movement. Thepawls 311 travel idly on the smooth peripheries of the segments 318until the pawls drop off such smooth edges, whereupon said pawls engageand rotate the ratchets 399 therewith an equal distance to the remainderof the travel of the arms 310 to 312 inclusive. For instance, if theprice per gallon pawl is set at 5 position, the pawl 311 will pick upthe corresponding ratchet 399 and rotate the ratchet and the gear 100live spaces. When the roller 369 leaves the arm 310 the cent order.

spring 313 restores said arm to its normal position, the pawl 311 movingidly over the ratchet teeth to its position on the periphery of thesegment 318. Each gear for the one 'cent order (Figs. 19 and 20) hasfour teeth thereon, 101, which are adapted to mesh with the teeth of asmaller pinion 102 on a sleeve 104. The gears 102 carry a pawl 103(Figure 22) fastened to their sides and adapted to engage internalratchet teeth 106 on the hub 101. The drums 101 are fastened to thesleeves 104 carrying on their opposite ends a gear 106 which meshes witha large gear 108 loosely mounted on the shaft 363. Rotation of the gear100, to the foregoing mentioned gearing, accumulates a tenth of a centin the said order which is disposed next to the left on the shaft 363 asshown in Fig. 21 and as hereinbefore described with respect to themechanisms of Figures 4 and 5. Due to the ratchet and pawl connectionhereinbefore described, movement of the Geneva gear 100 rotates thesmall gear 102 and through pawl 103 engaging the internal ratchet on thehub 101, rotates this hub in a counterclockwise direction. The hub beingfastened to the sleeve 104, will also rotate the sleeve in acounterclockwise direction and with it the gear 106 meshing with a largegear 106 on a shaft 363. The ratchet drive is utilized in the situationillustrated in order to prevent turning of the gear 102 and hence theGeneva gear 100 when the sleeve 104 is driven in a counterclockwisedirection by means of the gear 106 and the large gear 108. This sametype of ratchet drive is utilized in the two places indicated in Figure21 and also in the two places indicated in Figure 4'. Similarly the onecent order is transferred and accumulated in the ten cent order throughsimilar mechanism. In order to accumulate the tenths of a cent and thecents into the cents total sales dial, and of course without registeringthe tenths of a cent in the total sales dial, the following mechanism isprovided: By referring to Fig. 21 it will be seen that the last gear 108of a series of three of these gears is marked 108K. This gea'r mesheswith a smaller gear 110 on a sleeve 112, which rotates freely on shaft359. This sleeve H2 is rigid with another gear 114 meshing with a largergear 116 on a shaft 363, which gear 116 meshes with a small gear 118rotating freely on shaft 316, but having connected thereto a sleeve 120which carries rigidly therewith a total sales dial 122 carrying on itsperiphery numerals from zero to 9. This is the total sales dial for theone In order to accumulate the tenths of a cent order, the cents orderand the ten cent order into a total sales dial, (of a ten cent order),the following mechanism is provided:

Gear 100 on shaft 363 is provided with four teeth 101 which mesh attimes with its corresponding gear 102. rotating with a sleeve 104 whichin turn is provided with its .gear 106 meshing with a gear 124 meshingwith a smaller gear 126 on a sleeve 128 rotating the total sales dial129 of a ten cent order.

In order to accumulate the ten cent increments into the total sales dialof the dollar order, the following mechanism is provided: A gear 126 iscarried on the beforementioned sleeve 128 and this gear meshes with agear- 124 which drives a four-toothed gear 132 loosely mounted on shaft363. This four-toothed gear meshes with a smaller gear 134 which cariesa sleeve 136 in turn provided with a gear 138 which meshes with a largergear 140 in turn meshing with a smaller gear 142 on a sleeve 1, whichcarries with it the dollar order total sales dial "6. Each one of thetotal sales dials "8, I29 and 122 carries rotatably therewith a gearI48, 750 and I52 which in turn mesh with gears 154, I56 and 158 eachcarrying a beveled gear 160, I62 and 164 rotating in turn with otherbevel gears 166, I68 and H0, which drive sleeves I12 whereby to operateduplicate total sales dials on the opposite side of the clock face.

1 In order to drive dials for registering the total gallons andfractions thereof, the shaft 33'! carries a one-toothed gear I'll whichmeshes with a gear 118 which in turn drives a four-toothed gear 118fastened to it, gear I18 in turn meshing with a smaller gear 180 whichis fastened to the tenths of a gallon dial 182. Rotation of gear 116rotates a smaller gear 184 carrying a sleeve 186 provided with a gear188 which drives gear 190 and this gear in turn drives a gear 192fastened to the total gallon dial 194. Ina similar manner, the gear 190has fastened to it four-toothed gear 196, which meshes with a smallergear 198 carrying a sleeve 800 and another pinion 802 which meshes withgear 804 in turn driving a smaller gear 806 for rotating another totalgallon dial 808. These provide the three total gallon dials for thetens, units and fractions of a unit. The fractional units of a gallonare preferably indicated as from .1 to .9 of a gallon. Any indicia maybe used. In a similar way, each of these total gallon dials by means ofgearing illustrated in Fig. 21, drives duplicate sets of total gallondials on the opposite side of the clock face.

Shaft 33! has a gear BIO thereon which meshes with another gear 8|! onshaft 8 driving a worm 816 and a worm gear M8 for driving the totalgallon totalizer 820.

The resetting mechanism for this registering mechanism is similar to theconstruction hereinbefore described.

In order to provide the correct numerical sequence of the figurespresented on each of the dials on opposite sides of the clock face whenthey are driven from a single set of gearing, the usual type ofreversing mechanism indicated at 822 (Figure 17) is provided for thispurpose.

It is to be understood that whenever the term registering device orregistering means is used, it is intended to include either indicatingor recording mechanism.
